WebWe show that the limits of the method are mainly determined by speckle. With coherent light depth resolution cannot be increased considerably beyond the Rayleigh depth of focus. With partially coherent light a rms depth resolution of 68 μm at a distance of 380 mm (1:5500) was achieved. This resolution is 25 times better than the Rayleigh limit.

In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams.
